Milled Fibers Powder

Milled Fibers are finely ground fiberglass strands used to reinforce polyester and epoxy resin systems. Unlike lightweight fillers such as Q-Cel, Milled Fibers significantly increase the strength and durability of cured resin, making them ideal for high-load applications such as fin box installations, leash plugs, structural repairs, and reinforced bonding.

When mixed with resin, Milled Fibers create a high-strength composite that resists cracking and distributes loads more effectively than resin alone. They are commonly used by surfboard builders around fin boxes and other areas requiring maximum reinforcement.

Available in 8 oz, Quart, and 50 lb Bag sizes.
